York Mills, Ontario, Canada Application May25, 1942, SerialNo. 444,385 V In Canada Februaryl11,'1942 v f 2 cla s.(01. 25-. 1 s'1 My invention relates tofimpro'vements in forms formakingconcretefwalls and the like, and the objects of the-invention areas follows:

First the devising Ofa, form which is ileirible so as to be readilyadaptable to the construction of a wall of any desired area.

Second, the elimination of. lumber wasta e pioduced by cutting or,re-cutting of the lumber I transferred from job' to. job to .make itsuitable for use ineach job-and also by the spoiling of the lumberresulting from the tearing apart of 'a nailed together form.

Third, the obviating of holes in the form walls bored at each job forthe insertion of tie wires and the consequentweakening of the form.

Fourth, the elimination of metal wastage produced by throwing away. ofused and therefore bent nails, and'the substitution of securing meanswhich may be used repeatedly without damage to the form or tothemselves, and further saves the timeexpended in driving nails. p iFifth, the provision of a collapsible core used in conjunction with thewalls ofthe form for producing hollow walls. g

. Sixth, theprovisi'on of asc fr'old bracket construction which maybequickly and detachably mounted on any'portion of the form andtogetherwith the aforesaid objects the provision of a s rong, durable and rigidstructure which may he quickly assembled or disassembled and on whichnowork has to be done on the jjob other than the erecting ordismantling'ofthe form.

The invention consists essentially of. an. inner and outer wall eachcomprising spaced apart vertically set panels having undercut verticalinner edges, strips fitting the undercut edges,

horizontal and vertical liners, and detachable means for securing thestrips to the liners, the

strips serving.aslspacersbetween thepanels of v the form, ties formingspacers between the form walls: and .me'ans', for detachably securingthehorizontal to the vertical liners.

D and E are wood stripssecured to the looting at each side of its centre. Each wall portion Band C comprises panels I which may be made of ordinary wood or plywoodwith undercut vertical edges 2 andstrips 3 and 4 which are insertedbetween the panels and fit the undercut edges of two adjacent panels.The undercut edges are preferably in the form of rabbet grooves but maybe of any other form which will provide undercut edgesor the undercutedges may be entirely dispensed with as illustrated in Fig. 29.

The lower series of panels of the outer wall member are eparatedbycomplete strips 3 extending from X to X (see Fig. 3) the full heightof the panel and are provided with orifices 3 for the tie wireshereafter described. The re-v maining strips 4 are equal in length tothe dis- K tance between the horizontal liners F. Notches 5 are formedat the upper ends of each strip throu h which tie W re x d The liners Fare formed by upper and lower scantling members 6 and 'l held apart bycross pieces a which a e oosel placed on he lower m er 1 and, upo wh h hupper m m 6 is then placed. Each of the members 6 and l are p o i d wi hlongi udin l l ts and suitably spaced apart. The member 1 .of thelowermost linerv rests on blocks 'T 'which are placed on the footingstrip D or E carrying the wall members B or C,

The liners are spaced apart by verticals l provided with upper and lowercross pieces I l and v 2 which b ar r sp tively against the upper andlower faces ofthe members 6 and l at each side or the slots 9 and I0 andpins I3 and M which project into the slots9 and IQ of the upper andlower members 6 and I of adjacent liners F. I

The members 6 and 1 are secured to it er by the followinglocking device(see Figs. '7 and 8) which consist of a rod l having a T shaped ill)lower end [6 and an eyed upper'end I! in which is pivoted a cam 18 by ajournal pin 19. cam is operated by a lever 20.

The panels I are held in position by-the struts 2|, which are of therequired length to engage the upper edge of the panel of the desiredtier. The struts 2| engaging the upper edge of the lower tier before theerection of the upper tier is illustrated by dotted lines and those ening the upper edge of the second or upper tier being illustrated by fulllines. ar built to the top of the panelof the lower tier, the panel issecured to the liners near ts upper and lower edge by the followingdevice.

A keyhole slot 22' (see 11) is formed in the centre of the paneladjacent its upper andlower When the liners .24 slides.

edge (see Fig. 1). The keyhole extends partially through the panel theslotted portion of the keyhole being undercut on each side at 23. An eyebolt 24 is provided with a conical head 25 which is passed through thecircular portion 28 of the keyhole 22 and is then forced down to theposition shown in Fig. 9 to engage the undercut sides 23 of the slot.

A bracket formed by a portion 21 embraces the outer edge of a linermember 6 and has an up: standing portion 28 on which the eye of the boltWhen the bolt is slid vertically on the portion 28 it engages theundercut portions 23 and so locks the panel and liner together until "1the structure is complete.

Instead of the bracket 2'! and its portion 28 the bolt 24 may beprovided with a spike 29 (see Fig. 12) which is driven into the linermember 5.

Thedownwardly projecting portions 33 bear against the outer face of thehorizontal liners and brace the parts. A pin 33 extends through a slot35 so as to rest on the side portions of the bracket 36 and support theliner from vertical movement.

After the lower portion of the outer wall B has been built as abovedescribed, the lower portion of the inner wall C is built insubstantially the same manner and tied to the outer wall by a devicewhich I will now describe.

As before stated the remaining strips 4 are short strips provided withend notches which notches are in line with the interspace between anglepiece the upper and lower members 6 andlof the liners F.

Referring particularly to Figs. 3 and 15- Wires 46 are bent at theirends into loop form as at' ll and 4l Previously to the bending of thewire washers 42 having central orifices 43 and eccentrically placedorifices M are slipped onto the wire which passes throughthe' centralholes 33 and is then bent into the loops 4| and Q l the extreme endsbeing then passed through the orifices M and bent upward at 85 therebymost short strip 4 of the Wall E is'then placed in position; Thelowermost strip 4 is provided with an orifice W. The looped end 4l ofthe lowermost wire at is passed through the orifice Fi and the loopedend of the next wire through the notch 55 to project into theinterspaces be tween the two'lcwermost liner members. A hook. atmanually grasped by the handle 48 is passed between the liner memberstoengage each loop ll and M to which is pivotally connected a cam lever M.When the tie wire is in position and the lever ll pressed down theliners and struts are forced inward against the spacer washers #2locking the parts together and definitely spacing the wall members B andC apart. When this operation is complete another" strip l and tie Wirelfiis secured in position the operation repeated a' tie wire passing 7through each notch 5, until the top'of the panel is reached.

In setting up the upper tiers of panels it is necessary to use somedevice to hold the lower edges of the upper panel in contact with theupper edge oij'the lower panel previously set up. Preferably I use adevice shown in Fig. 14 which is made 'froma channel piece 49 having thecentre portions of the channel walls 50 andl turned down as at 52 andBefore setting the upper tiers in place the upper edge of the lower tieris engaged between the portions 52 and as indicated in Fig. 2, and thelower e of the upper panel inserted between the;

portions all and El thereby preventingthe upper panel slipping outofposition. When the upper panels are set up they are held inposition'by I the temporary braces 2i until the parts are bound togetherby the'tie wires as previously described. Alsg between panel and panelof the newly set up tier 2. channel member 54 extends across theinterspace and holds the panels in a line one with the other until theconnecting strips of the wall C and B are held together by the tiewires.

In conjunction with my wall construction I employ a scaffold bracket onwhich the scaffold boards 59 rest. Each scafiold bracket comprisesvertical bar 55 from each side of the upper wall Ni.

the bars" and 55. A strip 6| welded to the angle -piece extends up at anincline between the bars 56 as-clearly shown in'Fig. lfio-and isprovided with a downturned end 62 hooking into a slot 9 of an upperliner member 6. The lower end of the bar 55 is secured to the liner by abracket 35 of the type disclosed in Fig. 13.

In some cases the line of contact between an upper and lower panel I andI as in Fig. 25 is located between liners and not behind the uppermember of the liner as previously illustrated in Figs. 1 and 2. InFigure 25 a bar 65 extends between two liners to which are securedplates 66 61 fitting into the slots It! and 9 of the liners. Between thebar 65 a covering strip 68 is fitted covering the line of contact 63between the upperand lower panels preventing any tendency to movement atthe joint by outwardpressure.

111 Figures 18 to 21 is illustrated a collapsible core used for making awall having hollow insulating air spaces in the Wall. The core com-'inclined arms 73 at their lower end permitting the walls-to swingtogether towards the top of the core. Arms 12 are pivotally mounted onthe 'Ihe walls IE9 and ll are provided with undercut angular slots H(see Fig. 20) having two entrance openings l5 and Ft. TI is a saddlestrap having circular ends 58 and 19 adapted to pass through theentrance openings 15 and 1e into the horizontal arm of the slot 14 andis slid into the position indicated by dotted lines in the vertical armof the slot. at and jare tubes having endslots Si. Each arm 12 and E3has a head at each end as indicated at 82 and 83 which slip inbf) thetubes 80 and 89 and the arm slips into the slotsdl of the tubes. Thetubes 36 and the lowermost tube 80 pass through the saddle brackets "i?at each endoi the walls it and HI. r

The arms 72 are free of the wall I! and are held from movement by thehook bar 8t having a head at one end fitting the tube'fiil and engagingat its opposite end a pin'85 on the uppermost arm '52. 85 is a pull barhaving orifices Bl through which the tube se pass. When the A hook bar 33 is disengaged from the pin 85 the pull bar Bi: is pulled upward toswing up the arms '52 and so allow the walls 70 and ll to collapsetogether. The bars 12 and it and the lock part4 are held in the slots 8!by cotter pins fii (see Fig. 21). v

Notched bars 87 engage thetie wires ill and are held in place by thespacer sleeves 88. The

bars 8l form rabbet grooves 89, which form guideways for the walls 7E3and H of the collapsible form as 'it is slid downward when locked in theuncollapsedposition between the side walls end of which extendhorizontal bars 56. 51 is I of the mold.

In cases in which a window or other opening is located in the wall theform must be provided with an end wall Si] which slips onto the end ofthe core and extends the full height of the core so as to form a wallbetween the core end and window frame when the concrete is poured.

In Fig. 22 the connecting strips 5H between the panels 9| are formed tokey into the concrete so that when the form is dismantled the strips SIare left in the concrete and form a support to carry sheetingwhich isnailed thereto to form air spaces on the inside of the wall.

In Figures 23 and 24 means are illustrated to form the wall of rib.construction which maybe used in conjunction with the construction shownin Fig. 22. The panels SI of these figures carry hollow woodenprotuberances 92 which indent the wall to make the wall body thin at 93and form ribs Q4 between the. thin wall portions and in which the stripsSI are keyed.

In Figs. 28 and 29 I have shown a modified form or" panel construction.In this form the first erected wall member is formed by complete panels95 and 96, the vertical edges of which abut together and are providedwith opposing notches 8'. and 98 through which the tie wire 40previously described extend. Although I have shown opposing notches 9'!and 58 the notches might be formed completely in the edge of one panelonly the edge of the abutting panel being straight and unnotched.

The second erected wall member is formed as illustrated in 29 in whichpanels 99 formed with straight unnotched vertical edges are employed andinstead of intervening spacer strips horizontally divided panels IIJGhorizontally divided are employed. The panels 130 are dividedhorizontally into panel portions Ill corresponding to the strip portions4 and are provided with notches I62 and I93 formed on their upper edges.

The notches I62 and IE3 are horizontally opposite to the notches all and98 to permit the passage of the opposite end of the tie wire 40.Vertical and horizontal liners, as previously described, are employed inconjunction with the panels 95, 95, same manner as that previouslydescribed.

In Figs. and 31 I have shown a means for permitting free contraction ofa wall due to climatic or other conditions. In this construction IE3 andI35 are the walls of the form in. which the wall N35 is constructed.I'tll and I 03 are channel members secured to the inner faces of thewall members Iii-4 and I05 in opposing position and spaced a suitabledistance apart as illustrated. These channels preferably taper inwardand are provided with filling pieces I 58 formed integral therewith. v

Into the opposing channels It! and is slipped a dividing wall I69 formedof bituminous material which will allow of the free expansion andcontraction of the wall which is thereby formed in block sections freeto move longitudinally of the wall due to expanding or contractingaction. To prevent vertical movement I employ metal pins H8 secured infibre pieces III forming part of the wall I09 such pins being well oiledbefore the concrete is poured not to impede 89 and I80 in substantiallythe the free horizontal movement r the wall and yet prevent its verticalmovement.

When the wall is set and the form removed the recesses, H2 formed by theremoval of the channels I01 and I08 are filled with cement H3.

From the foregoing description it will be seen that I have devised aform which is readily adaptable to form a. wall of any desired area.

In order to lengthen the walls the strips 3 and 4 may be of any desiredwidth. The walls may be increased in height by inserting a panel equalin height to the spacing between the liners, thus increasing the heightabove-the normal panel height and'inserting a corresponding strip 4.

Any number of extra panel portions and strips to make the wall therequired height may be used.

I have also devised a form construction in which there is no nail orlumber wastage, no boring of holes in the panels to weaken thepanels,,and by which the form is quickly erected or dismantled and isstrong and durable.

When dismantling the form the loops of the tie wires are cut off and theloop and washer pulled out of the concrete. The cut end of the wire isthen bent into the hole left by the removed washer and the hole filled.

What I claim as my invention is:

i. In a wall form, the combination with a pair of opposing wall memberseach provided with horizontally spaced apart panels having their innerurface width less than their outer surface width, horizontally spacedapart liners bearing againstthe outer face of each member, and vertioalstrips fitting in the interspaces between the panels to form flush innerwall surfaces, the strips of one wall members being divided intosections extending between points located slightly below the uppersurface of each liner and having notches formed in an end of eachsection, and the opposing strip being in length equal to the height ofthe panel andhaving orifices therein in a line with the aforesaid,notches, and tie wires extending through each pair of aligned notchesand orifices and liners supporting each wall member and adapted to spacethe members definitely apart and simultaneously secure each wall memberto its corresponding liners.

,2. In a wall form, the combination with a pair of adjacent horizontalliners having vertically aligned'oriiices therein, of spacer strips,extending between the liners having projections extending into theorifices to hold the strips in place.
